Release Highlights

  • IANA Data 2014j
    JDK 8u31 contains IANA time zone data version 2014j. For more information, refer to Timezone Data Versions in the JRE Software.
  • SSLv3 is disabled by default
    Starting with JDK 8u31 release, the SSLv3 protocol (Secure Socket Layer) has been deactivated and is not normally available. Please see the jdk.tls.disabledAlgorithms property in <JRE_HOME>\lib\security\java.security file. If SSLv3 is absolutely required, the protocol can be reactivated by removing "SSLv3" from the jdk.tls.disabledAlgorithms property in the java.security file or by dynamically setting this security property before JSSE is initialized.
  • Changes to Java Control Panel
    Starting with JDK 8u31 release, SSLv3 protocol is removed from Java Control Panel Advanced options. If the user needs to use SSLv3 for applications, re-enable it manually as follows:
    • Enable SSLv3 protocol on JRE level: as described in the previous section.
    • Enable SSLv3 protocol on deploy level: edit the deployment.properties file and add the following:

      deployment.security.SSLv3=true

For a list of bug fixes included in this release, see JDK 8u31 Bug Fixes page.

Java Expiration Date

The JRE expires whenever a new release with security vulnerability fixes becomes available. Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Third Party Bulletin. This JRE (version 8u31) will expire with the release of the next critical patch update scheduled for April 14. 2015.

For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u31) on May 15, 2015. After either condition is met (new release becoming available or expiration date reached), Java will provide additional warnings and reminders to users to update to the newer version.
